RPG Stack by the numbers

The AI behind character generation, the rules assistant, NPCs, scene tools, story mode, and the Virtual GM now runs on Anthropic's newest Claude Sonnet model, Sonnet 5, the current generation of the model we already used. Credit costs are unchanged.

Fixed two things that had quietly stopped working. On any system reference page you can once again suggest a correction, and see and vote on other people's suggestions, with well-supported edits auto-approving once they pass the community vote threshold (submitting and loading corrections had been failing behind the scenes). And when you share a character, its public page now uses that system's own sheet with a proper read-only view for visitors, instead of sometimes rendering every character through the Vampire layout.

We fixed a class of bugs where several AI features could fail right after generating, so you would spend credits and then hit an error instead of seeing your result. This hit character tools (scene summaries, reaction ideas, writing help) and the game-master tools (session prep, plot hooks, party dynamics, story-so-far recap) alike. Every AI feature is now validated end to end, so if a generation ever does fail the credits it used are refunded automatically and we are alerted right away instead of it breaking quietly. For game masters, all the campaign AI tools now live in one "GM tools" tab inside a campaign, and any tracked thread with a description gets a new one-click summary that condenses a long roleplay thread into its key events, unresolved points, and standout character moments.

We hunted down and fixed a bug where editing a character sheet could silently fail to save, so changes weren't actually being kept (it hit some sheets, including Mage and Werewolf, the hardest). Autosave is rock-solid now across every sheet: your edits save automatically as you go, and they're kept even if you close the tab, navigate away, or are on mobile mid-edit. We also closed the same silent-saving gap in a few more places, scene contributions, campaign notes, threads, and timeline events now reliably save and clearly tell you if something goes wrong instead of quietly dropping what you typed. And if a save ever does fail, we're now alerted instantly so we can jump on it. Plus a batch of smaller fixes: advancement won't let you raise a trait you can't afford, an expired session now prompts you to sign back in instead of losing your work, the initiative tracker's combat controls work again, and several pages that could error out now fail gracefully.
